lilipj opened a new issue #17395: Keras model to ONNX to mxnet error URL: https://github.com/apache/incubator-mxnet/issues/17395 ## Description I'm trying to import a keras model converted in onnx format with onnx_mxnet import module. I've built a classic mnist digit classification with keras : def define_model(): model = Sequential() model.add(Conv2D(32, (3, 3), activation='relu', kernel_initializer='he_uniform', input_shape=(28, 28, 1), name="name_1")) model.add(MaxPooling2D((2, 2), name="name_2")) model.add(Conv2D(64, (3, 3), activation='relu', kernel_initializer='he_uniform', name="name_3")) model.add(Conv2D(64, (3, 3), activation='relu', kernel_initializer='he_uniform', name="name_4")) model.add(MaxPooling2D((2, 2), name="name_5")) model.add(Flatten(name="name_6")) model.add(Dense(100, activation='relu', kernel_initializer='he_uniform', name="name_7")) model.add(Dense(10, activation='softmax', name="name_8")) # compile model opt = SGD(lr=0.01, momentum=0.9) model.compile(optimizer=opt, loss='categorical_crossentropy', metrics=['accuracy']) return model I've used keras2onnx to convert my model and save it in a .onnx file When i import the model with onnx_mxnet.import_model() function, I've got the following error Traceback (most recent call last): File "/home/aurelie.peter/WORK/mnist_handwritten_digit_classification/onnx_to_mxnet.py", line 37, in <module> sym, arg, aux = onnx_mxnet.import_model(onnx_model_file) File "/home/aurelie.peter/anaconda3/envs/onnx/lib/python3.7/site-packages/mxnet/contrib/onnx/onnx2mx/import_model.py", line 59, in import_model sym, arg_params, aux_params = graph.from_onnx(model_proto.graph) File "/home/aurelie.peter/anaconda3/envs/onnx/lib/python3.7/site-packages/mxnet/contrib/onnx/onnx2mx/import_onnx.py", line 115, in from_onnx inputs = [self._nodes[i] for i in node.input] File "/home/aurelie.peter/anaconda3/envs/onnx/lib/python3.7/site-packages/mxnet/contrib/onnx/onnx2mx/import_onnx.py", line 115, in <listcomp> inputs = [self._nodes[i] for i in node.input] KeyError: 'name_1/kernel:0' ### Error Message /home/aurelie.peter/anaconda3/envs/onnx/bin/python3.7 /home/aurelie.peter/WORK/mnist_handwritten_digit_classification/onnx_to_mxnet.py Traceback (most recent call last): File "/home/aurelie.peter/WORK/mnist_handwritten_digit_classification/onnx_to_mxnet.py", line 37, in <module> sym, arg, aux = onnx_mxnet.import_model(onnx_model_file) File "/home/aurelie.peter/anaconda3/envs/onnx/lib/python3.7/site-packages/mxnet/contrib/onnx/onnx2mx/import_model.py", line 59, in import_model sym, arg_params, aux_params = graph.from_onnx(model_proto.graph) File "/home/aurelie.peter/anaconda3/envs/onnx/lib/python3.7/site-packages/mxnet/contrib/onnx/onnx2mx/import_onnx.py", line 115, in from_onnx inputs = [self._nodes[i] for i in node.input] File "/home/aurelie.peter/anaconda3/envs/onnx/lib/python3.7/site-packages/mxnet/contrib/onnx/onnx2mx/import_onnx.py", line 115, in <listcomp> inputs = [self._nodes[i] for i in node.input] KeyError: 'name_1/kernel:0' ## To Reproduce The digit model comes from https://machinelearningmastery.com/how-to-develop-a-convolutional-neural-network-from-scratch-for-mnist-handwritten-digit-classification/ I've added the following lines onnx_model = keras2onnx.convert_keras(model, model.name) # converts the keras model to ONNX object. onnx.save_model(onnx_model, 'model.onnx')# save the ONNX object into .onnx file. And in another script python I import the onnx model import mxnet as mx import mxnet.contrib.onnx as onnx_mxnet from mxnet.test_utils import download onnx_model_file = download("model.onnx") sym, arg, aux = onnx_mxnet.import_model(onnx_model_file) ### Steps to reproduce (Paste the commands you ran that produced the error.) 1. 2. ## What have you tried to solve it? 1. 2. ## Environment Keras : 2.3.1 keras2onnx : 1.6.0 tf : 2.0 We recommend using our script for collecting the diagnositc information.
